In addition, when using this AC corona discharge, the charge required for static elimination is generated only during a part of the half cycle when the voltage applied to the discharge electrode has the opposite polarity to the charged polarity of the object, so the static elimination efficiency is not good. Therefore, DC corona discharge type static eliminators are also used, which can continuously generate charges of the polarity required for static elimination. In all of these, in order to efficiently eliminate static electricity by corona discharge, the discharge electrode is provided in an exposed position facing a charged object.

The envelope is provided with an opening at a position facing the charged object, and is provided with a gas supply device that blows gas from the discharge electrode side toward the charged object through the opening, so that ions reach the charged object. promote. In addition, in order to promote the arrival of ions to a charged object and effectively eliminate static electricity, it is preferable to use a direct current corona discharge. A voltage is applied, and a negative DC voltage is applied to the second discharge electrode, and static electricity is removed from the traveling charged object by the first discharge electrode, and then by the second discharge electrode. Furthermore, in order to suppress the diffusion of corona light generated at the discharge electrode, the envelope is preferably made of a light-absorbing black material, or its inner surface is coated with a light-absorbing black material. Preferably, a light shielding plate is provided to surround the acicular electrode constituting the discharge electrode, and the discharge electrode is also made of a black insulating material to prevent corona light from leaking from the opening of the envelope.
